Management Authority for Urban Railways Chapter 6 – Estimated Capital and O&M Costs
6.3 Operating and Maintenance Cost Estimates
6.3.1 Introduction
151. The annual operating and maintenance (O&M) cost estimates for Line 2 have been estimated
for 2015, 2025 and 2035.
152. The O&M cost is the sum of the following two main categories of costs:
Staff costs: cost estimation for the whole staff: administrative, operation, maintenance and
engineering;
External costs such as cost of electricity, materials and consumables.
6.3.2 Personnel Costs
153. The annual personnel cost is calculated following the organization and staffing described in
Appendix E. The organization is a simple structure with a General Management (including counselling
and quality control) and three line departments: Operations, Maintenance and Administration. The
total estimated manpower requirements for operations and maintenance are 780, 800 and 814 for
2015, 2025 and 2035 respectively.
154. For the purpose of staff cost estimation, the staff was split in the following 6 categories
(estimated annual salary in US$ in early 2008 in parenthesis):
Employees in managing position (US$6,485)
Administrative and managerial clerks, OCC supervisors, engineers (US$5,650)
Drivers (US$5,089)
Station supervisors, skilled workers ((US$3,724)
Secretaries, drivers, platform ticket controller, security staff(US$2,767)
Unskilled workers (US$2,523).
6.3.3 External Costs
155. The electricity consumption is based on trains (traction and auxiliary on-board equipment),
stations and depot consumptions. The onboard auxiliary equipment consumption is function of the
time when trains are switched on. It was considered 15 hours a day for each train and 50kWh for the
auxiliary consumption. For underground stations, the required power supply was estimated in 950 kW.
For elevated stations, the required power supply was estimated in 270 kW. For depot, it was
considered a total power consumption of 1 MWh.
156. The electricity price, considering it will be supplied by a voltage of 110 KW, is determined in
early 2008 as the following:

157. The consumables category includes all the necessary material and fluids to operate and
maintain the system: lubricant materials, sand, water and detergents. This category also includes the
power supply for administrative and maintenance buildings (lighting, power, air conditioning). Based
on experience, this cost item is assumed to be 15% of staff cost.
158. This materials category includes all the material pieces to be bought for the maintenance
activity, the outsourced maintenance for specific equipment such as electronic parts, optical fiber
components or computers, with 70% considered of foreign source and 30% of local source. The
